Term - Newton rings
|Newton rings||SWPP Photographic Glossary|
Friday 28th February 2020
A series of concentric circles that appear on a scanned image when a thin layer of air exists between the glass scanner bed and the image being scanned. Newton rings appear when light waves are reflected from both top and bottom surfaces of the air between the glass and the image, interfering with the resulting scan.
